Seed preservation has a long history. In order to better develop production, agricultural workers need to properly preserve seeds to ensure that there are enough seeds available for sowing in the coming year. With the development of science and technology and the improvement of germplasm resources protection and utilization requirements, the preservation of germplasm resources has begun to adopt a more advanced method, that is, to build a germplasm resource library to achieve the purpose of long-term storage of germplasm. Here we will briefly introduce what exactly is a germplasm resource library? And the requirements for the selection of the location of the germplasm resource library. 1. What is the germplasm resource library The germplasm resource library is a warehouse that uses instruments and equipment to control the storage environment and stores crop germplasm for a long time, also known as a gene library. Excavate and collect seeds of various crop varieties and store them scientifically, so that the germplasm still has the original genetic characteristics and high germination ability after decades or even hundreds of years. For the improvement of varieties, cultivate high yield, high quality, New varieties with strong resistance to stress, and it is of great significance to provide abundant germplasm and research materials for the theoretical research of biology. 2. The location selection of the germplasm resource library From the perspective of long-term development, at present, many regions have put forward reasonable germplasm resource protection and utilization programs for the unique resources of the region. Among them, the construction of a germplasm resource database is one of the effective methods adopted in the program. The demand for the construction of the resource library is still relatively high, and before the establishment of the germplasm resource library, the selection of the library site is very important. Generally speaking, the selection of the library site of the germplasm resource library should meet the following requirements: ①Proximity to agricultural scientific research units, and there is an appropriate amount of cultivated land for breeding; ② Stable temperature, low humidity, and good greening conditions are conducive to saving construction investment and operating costs; ③ Good geological conditions, low groundwater level, and easy to drain rainwater; ④Convenient transportation, reliable water and electricity supply, located upstream or upwind of the pollution source; ⑤Variety resource library for processing data by computer, the location of the library should be far away from strong electric field, strong magnetic field and strong vibration source to ensure the safe and reliable operation of the computer.
